Abstract

NIESZPOREK, Jolanta. The inhibiting or accelerating effect of different surfactants on electroreduction of Zn2+. S.Afr.j.chem. (Online) [online]. 2014, vol.67. ISSN 1996-840X.

The course of differential capacity curves of the electric double layer at the mercury electrode/surfactant solution interface was described for three different surfactants from different groups. Using square-wave voltammetry (SWV) it was found that the surfactants had a varying effect on the kinetics of electroreduction of Zn2+ ions. Simple relationships were presented between SWV peaks and the course of differential capacity curves in the presence of surfactants as compared with the curve of differential capacity for the basic electrolyte.

Keywords : Electroreduction; sodium 1-decanesulfonate; N-decanoyl-N-methyl-glucamine; octyltrimethylammonium bromide.
